Embodiment
Hereinafter will describe the present invention with reference to the accompanying drawings and in conjunction with the embodiments in detail.Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
Fig. 2 is the schematic diagram according to the server of the embodiment of the invention, and this server 1 comprises veneer 10, and this veneer 10 comprises: each other Rong Yu first communication port 102 and second communication port one 02 '; And central processing unit (Central Processing Unit, central processing unit) 100, be used to detect first communication port 102 and second communication port one 02 ' state; When the state that detects first communication port 102 for unusual (can comprise unusually break down, packet loss and loosening) and second communication port one 02 ' state for just often, with the business of first communication port 102 switch to second communication port one 02 '.
In the correlation technique because occur unusually in the key hardware of mainboard, when particularly communication port such as network interface breaks down, can cause the frequent masterslave switchover between the veneer, in each masterslave switchover process, all can carry out the migration of a large amount of communication traffics, the synchronous of mass data can appear between main and standby boards, thus traffic affecting normal transmission and processing.Present embodiment is owing to carry out Redundancy Design is provided with redundancy for original communication port of this veneer communication port on each veneer, one can switch to another with business when breaking down in first redundant each other communication port and second communication port, the number of times of switching between the veneer that causes thereby the network interface service quality that reduces effectively and avoided communication port owing to mainboard to break down causing descends has improved the stability of server and user's experience.
Preferably, CPU 100 also be used for when the state that detects first communication port 102 for normal and second communication port one 02 ' state when being unusual, with second communication port one 02 ' business switch to first communication port 102; When detect first communication port 102 and second communication port one 02 ' state be when unusual, the business of veneer 10 (as veneer 1) is switched on another piece veneer 10 (as veneer 1) on the server 1.Like this, only when the first redundant each other communication port and second communication port all break down, just start the masterslave switchover between traditional veneer, and first communication port and unusual probability of second communication port while are very little, thereby further reduced masterslave switchover number of times between veneer, further improved stability and the reliability and the user experience of server.
Wherein, above-mentioned communication port is the light mouth/electricity mouthful (being network interface) of veneer.Above-mentioned server can be the IPTV multimedia server.Can comprise a plurality of aforesaid veneers 10 in each server, also can comprise in each veneer many to the first redundant each other communication port 102 as implied above and second communication port one 02 '.
As shown in Figure 3, server according to first preferred embodiment of the invention, with the communication port on the veneer of server is that network interface is an example, on main and standby boards, every veneer all exists N to two redundant each other network interfaces, as: Eth1 and Eth1 ', Eth2 and Eth2 ' ..., EthN and EthN '.If like this because have one to break down to external port, just do not need to enable switching between the veneer, a bit imperceptible network interface of application program breaks down, because protocol layer can carry out the transmitting-receiving of data from the another one network interface.All break down if find redundant each other first communication port and the second communication port on this veneer, need enable the flow process of switching between the veneer this moment so.According to the demand of reality, Rong Yu two network interfaces can be set to have identical MAC and also can be arranged to have different MAC each other.
As shown in Figure 3, the network interface on every veneer all is connected on the switch by netting twine, and wherein, different network interfaces can be connected to according to concrete applicable cases on a plurality of different switches.Each veneer is provided with two row network interfaces, the corresponding respectively redundant network interface that partners of network interface Eth1 ', Eth2 ' on network interface Eth1, Eth2 on first horizontally-arranged, Eth3 and second horizontally-arranged, Eth3 ' (according to the line position that goes out of exchange chip, active and standby network interface may not be fully by the horizontally-arranged correspondence).Main redundant each other network interface with the every row on veneer and the standby board is connected on the switch by netting twine respectively.Business switch method according to the server of first preferred embodiment of the invention may further comprise the steps:
Step 2, the state that CPU detects first redundant each other network interface (for example being Eth1) and second network interface (for example being Eth1 ') is all normal, can only allow one in first network interface and second network interface to carry out data transmit-receive, also can allow first network interface and second network interface respectively handle a part of data.
Step 3 when CPU detects the abnormal state of first network interface, switches to the business datum of first network interface on second network interface.When the state that detects first network interface when being unusual, business is switched to first network interface for the state of normal and second network interface.In both cases, data are all handled and alarm notification network interface abnormal state on the normal network interface of state.
As shown in Figure 4, when the first network interface Eth1 breaks down when causing link 1 to break down, the application program on upper strata can also be by the second network interface Eth1 ' from link 1 ' go up transceive data; Just often can be at link 1 and link 1 ' all according to selection of configuration link transmit-receive data wherein; When link 1 and link 1 ' when all breaking down, restart the masterslave switchover flow process between the veneer.But the probability that the situation that two links (the promptly redundant each other first network interface Eth1 and the second network interface Eth1 ') all break down occurs is extremely low.In whole process, the application program on upper strata need not to be concerned about in the upper strata packet receiving packet from which network interface transmits.
